` 4 claims. (ci. v2er-.81u

This invention relates in general to liquid dispensers andmore particularly to a form of dis# penserl adapted for use inihospitals, sanitariums and in other places where rel'ativelylarge volumes of disinfectant,"antiseptic, solutions and liquid soapY arevdispensed, and has for an object the provisionof a container of substantial capacity arranged to be mounted either against and secured to a wallor other supporting structure orv as a detached unit having a suitablev base for supporting it against displacement from a predetermined position.

Anotherobject is `to"provide in a dispenser of the` character and for the purpose mentioned, a container having a dispensing spout at its top and a foot operated pressure creating unit at its bottom` and so connected with the interior of the container' and withl the dispensing spout that at each operation of the' foot controlled pressure unit asubstantiai quantity of liquid will be dis'- pensed from said spout byreason of the pressure created in the dispenser. v

Amore detailed object is to provide within the container and near its bottom a submerged checl';` valve connected `with the discharge chamber of said pressure unit and also with a tube leading upwardlyV Within theV container to` and connected with the dispensing spout so that when pressure is applied to the` tube througlrthe medium of the pressure unit the column of liquid in the tube will bey el-evated' to a point of discharge from the spout and when pressure `is relieved theV liquid. in the tube willA bel held against draining vbackwardly' into the container, dueto the presence in the supply lineV tothe spout of said check valve.

Other obects of invention may appear as the* description of my improvements progresses.

I' have'sh-own in the accompanying drawing a preferred form of device,A subject' to modification, within the scope of' the appended claims, without departingvfrom the spirit of my invention. 4In said drawing. y

Fig. 1 is a sectional elevation of an assembled dispenser embodying my improvements' .showing one form of unit: ,y

Fig', 2 is a top plan thereof;

Fig". 3 is an elevation of" a wall type dispenser, partly in section; Y p

Fig. 4 isa top plan of the same;Vv and Fig'. 5' is an enlarged sectional A'elevation of the valve housing" ofFig. 1, showing details of' con-1l struction.` l

It Willbe noted. that the two forms of dispenser shown in the drawing arey exactly the same in principle and they differ in structure only as may be necessary totadapt `one form to use as a de.-

tached unitas in Fig. 1, and the other form as a wall unit,- as in Fig. 3.

Brieiiy described, my improved dispenser includes a vertically vdisposed container C ofsuiiicient size and capacity to hold several gallons of liquid. Said container is adapted to be supported as' by means of a suitable base B, as in Fig. 1, wherein the container is shown as or" cylindrical form attached to the base at its bottom and having a capA witha filler plug or cover I adapted to cover a suitable opening 2 through which the contents .ci the container may be replenished, and adispensing spout S extending outwardly from said cap, as shown. Or, as shown in Fig. 3, the container C may be of rectangular or other cross sectional form and have a bracket B formed thereon or attachedV thereto for the purpose of` supporting the container on a wall or other suitable supporting structure. In the latter form a ller la is provided at the top of the container and covered by a closure lb, said4 filler having an opening 2a in the bottom thereof, and a dispensing spout 2 similar toor different from the form shown in Fig. 1 is attachedto the top of the container as hereinafter described.

in each of the herein described forms of device a footoperated pressure unit P is provided for association with the container and may be mounted in the base B of the form shown in Fig 1 or' supported on the floor and detached of tube 5.

Valve `housing 4 has a vertical chamber lil from the container mounting, as shown in Fig. 3. vContainer C', in either case, has a vertically disposed tube T mounted therewithin and conn nected at its upper end to a fitting 3 and at its lower end to a valve housing 4 which is submerged in the liquid of the container and ris positioned near the bottom of the container, as

shown. l

Fitting '3 has a chamber 5 therein and carries an outwardly extended tube 5 which forms a part of the dispensing spout S and the passage E thereof isv in constant communication with chamber 5 and ythevertical passage 1 of tube T. Spout S also includes an elongated outer section of tube '8, the outer end. of which is bent downwardly to form a spout and the inner portion of which is telescopically extended into the passage 6 of tube 5 and is held in. adjusted position by means of a coupling 9 which is threaded onto thel outer end therein which is in constant communication with an offset passage 'I of tube', and alsovhas a transverse part I'l' affording communication be'- tween chamber I and a valve chamber I2 in the offset portion of housing 4, said chamber I2 having an inlet port I3 in the bottom thereof adapted to be closed by means of a ball check valve I4 which finds a seat over the upper end of said port in the bottom of chamber I2. Chamber I2 has a plug I 2a forming a top closure and is removable for inserting ball I4. Plug I2a has a depending portion |22) which limits the upward movement of ball-f|4 so asnot to close port I I.

Pressure element P includes a base' I5 either as a unit as in Fig. 3, or formed in the base B, as in Fig. 1, and a detachable cover I6 secured thereto 'f as by means of screws II. A flexible diaphragmHV i I8 is clamped between the members I5 and I6 so as to provide a pressure chamber f I 9 in which a compression spring 20 is mounted forurging the diaphragm outwardly in the direction of the'c'over I6, as shown. A foot operated plunger 2 I is slid ably mountedon. member I6 for operating the*- raised sufcientlyat each operation of the presu sure unitI to replenish fthe quantity Of liquid in tube T andassociated vpartsV butcloses port I3 at the''completion of each operation so as to retain the liquid' in said parts.

,It is quite apparent that at each operation of pressure'unit P afslibstantial quantity ofV liquidA willbeejected from spout S and the continued operation thereof will; provide 1ample quantities of liquid for any requisite use and fargreater quantities than 'could be obtained from Well known types of handl operated dispensers such as are employed in laboratories or lavatories for individual usage. j ,A y Y Irdesiredthe'sp tf S maybe arranged so as to" swing to any desirdwposition'over thetop of the'container C'by merely providing the member 3 with a swivel mounting `or arranging said member so as .to rotate onthe top ofthe container.
